Overview
The Detu testo440 portable wind pressure and speed meter (SF free shipping) can measure quickly and easily. This multifunctional instrument automatically detects each connected probe, which means you don't need to manually reset the measurement parameters when replacing the probe. The clear structured measurement menu is used for measuring air volume, air hood, pressure difference and K coefficient, determining turbulence, determining heating/cooling output efficiency, mold detection and long-term measurement, providing support for you.
Product Details
Detu testo440 portable wind pressure and speed meter (SF Express free shipping)Product Introduction
Use the testo 440 dual universal measuring instrument combined with high-quality probes to measure and store all indoor air quality parameters. Three types of probes can be connected simultaneously: a Bluetooth probe, a wired probe, and a temperature probe with a K-type thermocouple. The automatic probe detection and structured measurement menu ensure simple operation, making your daily work easier.
The testo 440 wind pressure and speed detection kit is used for air volume measurement. It is an L-shaped pitot tube made of stainless steel, with a length of 500mm and a diameter of 7mm. The differential pressure range is -150~+150 hPa, and a pressure probe is connected to measure the flow rate. The measurable range of wind speed is 1-100 m/s. When measuring wind speed in high wind speed, high dust ventilation ducts or process air, it is recommended to use pitot tubes.
